The Hulk Cheats

Enter these cheats at the code input screen in the Options menu:

When a tank has its shield up, you cannot go through it, but your Gamma Claps can. It also reduces the withstanding. You will find health and rage.

Unless you are Super Hulk, Alphas can withstand a full powered gamma blast, but soldiers cannot. You can tell them apart by the color of their uniforms.

In challenge mode, go to time attack mode 1. Wait until the soldiers appear. Go to either side of the building. Pick up a soldier, jump, and throw him off the building. Sometimes another soldier will wave good-bye to him.

The super-robots are the steel-made hide-weaponry guards inside the Desert Base. To defeat them, get them to clump together. Then, jump over the pack of them and run in a circle around them. They will use their energy-beam attack, but as you run it will hit more robots, damaging or destroying them all.

Perform any kind of punch toward a missile when it is flying at you. If timed correctly, you can punch the missile and it will fly back to the soldier who shot it then blow him up.

After defeating the Leader, the stronghold will collapse. Pound the door two or three times and follow the path. Ignore the Gamma Elite and go directly to the place where you fought Madman and Half-Life. Wait until the boulders stop falling. Then, jump as if going out of a trouble zone. Defeat the return of Madman at the end and you are home free.
